GRAIN-TRANSFER MECHANISM FOR PLANTERS.

To all whom it may concern Be it known that I, JOHN A. lrnninisos, acitizen of the United States, residing at- Geneseo, in the county ofHenry and State of Illinois, have invented a new and usefulGrain-Transfer Mechanism for Planters, of which the following is aspecification.

This invention relates to an improvement in grain transfer mechanisms.

The primary object of the present inven tion is to provide a simple ande'l'l'icient grain transferring mechanism for transferring the grainfrom one hopper off a planter to another.

The present invention is an ll'llPlOVClllCllt on the transfer mechanismshown in Patent 911,691 granted February 9, 1909. In that patent a mainhopper is shown said hopper being arranged above a delivery hopper, agrain sorting mechanism being interposed between the two hoppers. Graindeposited within the first hopper and the selecting mechanism receivesthe grain and deposits a portion of the same within a suitable chute,the portion of the grain which is rejected by the selecting mechanismbeing returned to the other hopper. The grain is then conveyed by meansot a con veyer back to the delivery hopper, a rotary wiper beingarranged within the second hopper to return the rejected grain to theconveyer. The arrangement of the hoppers and the construction of thegrain selecting mechanism is substantially the same as that shown in theabove mentioned patent, this invention as before stated being animprovement in the elevating mechanism.

In the drawings: Figure 1 is a side elevation of the elevatingmechanism. Fig. 2 is a section taken on the line 2-2 of Fig. 1.

In the drawings 10 designates a vertically disposed tube the upper end11. of which is provided with a spout 12 arranged to communicate withthe upper hopper 14L. A sleeve 17 is secured to the upper hopper andsupports the tube at a point adjacent its upper end, a sleeve 18supporting the same adjacent its lower end. The lower hopper 16 isprovided with a chute 19 to which the lower sleeve 18 may be secured orwith which said sleeve may be formed integral, said chute registeringwith an opening 20 formed in the tube 10, the tube being solid belowthis point. It will thus be Specification of Letters Patent.

noted that the rejected grain deposited with in the grain hopper 16 willbe conducted by means of the wipers 21 which rotate with the selectingmechanism into the chute I and to the tube 10. Secured to one ol' theextensions 22 ot the sleeve .17 is a coiled spring 25, the other end ofwhich is connected to the lower end of the tube 10, the tendency of thesaid spring being to hold the tube in its extended upper position.Secured to the sleeve 18 is av spring 2:; which is provided with anelongated loop 26 which passes through an eye 27 secured to the tube.-irranged centrally on the tube is a collar 28 which is provided with aprojection 28 which is .in the path ()1? a cam 29 arranged on the shaft30, this cam being of a configuration which will depress the tubethrough its contact with the projection twice during each revolution oilthe shaft. Thusv it will be noted that when the cam forces the tubedownward the same will be returned to its normal position by means ofthe spring 2&5, the spring preventing the same t'rom pa 1'- ticipatingin too great an urnvard movement. As the tube is pressed downward thespring 25 will not be disturbed, the eye sliding in the loop 26. Thispeculiar inannero't mounting the tube causes the same to vibrate as theshaft 30 is rotated. The rejected grain is being constantly depositedwithin the tube and the vibration of said tube will l'ecd the sametoward the spout '12, the grain being deposited within the hopper ll. .sthe grain within the tube is forced upward, a certain quantity isprojected through the spout. \Vhile this grain is projected through thespout, the entire stat-ll" oi: grain is forced upward leaving a space atthe bottom of the tube, which space is tilled by a fresh supply of grainfrom the lower hop-- per. Thus the upward movement of the stack projectsa certain quantity of the grain within the upper hopper, the space leftwithin the tube by the removal of said grain being filled from the lowerhopper.

The many ad vantages of a transfer mechanism of this character will beclearly apparent as it will be seen that the same will effectuallyconvey the grain from one hopper to the other, attention being called tothe fact that the same may be used in connection with planters. otherthan that 1llllstrated 1n the drawings. It wlll also be seen that thestructure is such. as may be easily and economically manufactured andthe va rious parts readily assembled.

What is claimed is 1. In a conveying mechanism, a plurality of hoppersarranged one above the other, a tube one end of which is closedsupported for vertical movement by said hoppers and means for vibratingsaid tube to transfer material from one hopper to the other, said meansimparting a more rapid movement to the tube in one direction than in theother.

2. In a conveying mechanism, a tube one end of which is closed supportedfor vertical n'mvement, said tube being in communication with aplurality of hoppers and means for causing said tube to vibrate totranster the material from one of said. hoppers to the other, said meansimparting a more rapid movement to the tube in one direction than in theother.

3. In a conveying mechanism, a plurality of hoppers arranged one abovethe other, a tube one end of which is closed supported for verticalmovement by said hoppers, a resilientconneetion between the upper hopperand the lower end of said tube, a resilient connection between said tubeand the lower hopper and means for imparting ver tical movement to saidtube.

l. In a conveying mechanism, a plurality of hoppers arranged one abovethe other, a sleeve secured to each of said hoppers, a tube one end ofwhich is closed supported for movement by said sleeves, a collar securedto said tube, a projection on said. collar, a shaft, a cam mounted onsaid shaft and a resilient connection between said tube and saidhoppers.

In a conveying mechanisnii, a plurality of hoppers arranged one abovethe other, sleeves supported by said hoppers, a tube one end o'l. whichis closed supported for movement by said sleeves, a resilient connectionbetween the upper hopper and the lower end of said tube, a resilientconnection between the lower hopper and said means for impartingmovement to said sleeve, said last mentioned. connection being activeonly during the movement of the sleeve in one direction.

6. In a conveying mechanism, a plurality o1 hoppers arranged one abovethe other, a sleeve supported by each of said hoppers, tube one end or".which is closed supported for movement by said sleeves, a spring hav ingone of its ends secured to the upper hopper and the other to the lowerend of said tube, a spring having one of its ends secured to the sleevesupported by the lower hopper, the other end of said spring terminatingin an elongated loop, an eye supported by the tube, the looped end otsaid spring passing through said eye and means for imparting movement tosaid tube.

7. In a conveying mechanism, upper and lower hoppers, an upwardlyextending tube closed at its lower end and communicating adjacent saidend with the lower hopper and at its upper end with the upper hopper,yielding means for holding the tube nor mally elevated, and means forgradually lowering the tube against the stress of said yielding meansand suddenly releasing it.

8. In a conveying mechanism, the combination with an upper and a lowerhopper of a tube communicating adjacent its lower end with the lowerhopper and at its upper end with the upper hopper, the lower end of thetube being closed, and separate means for gradually lowering the tubeinto communication with the lower hopper and quickly releasing the tubesuccessively to teed material upwardly within the tube into the up perhopper.

in testimony that I claim the foregoing as my own, I have hereto atlixedmy signature in the presence of two witnesses.
